Slammed into piller

Linally I found my nerve. I lunged at the thing that used to be Luke, thrusting my blade straight at his chest, but his skin deflected the blow like he was made of pure steel. He looked at me with amusement. Then he flicked his hand, and I flew across the room.
I slammed against a pillar. I struggled to my feet, blinking the stars out of my eyes, but Kronos had already grasped the handle of his scythe.
“Ah...much better,” he said. “Backbiter, Luke called it. An appropriate name, now that it is re-forged completely, it shall indeed bite back. ,,
“What have you done to Luke?” I groaned.
Kronos raised his scythe. “He serves me with his whole being, as I require. The difference is, he feared you, Percy Jackson. I do not.”
